Review Pull Requests with git worktrees

Sometimes you get a PR on a project, but cannot review it without wrecking your current working setup. This might be because it needs to be compiled, or a new set of requirements. Git worktrees is a great way to chekout the remote branch in a completely separate directory to avoid changing any files in your current project.

# pattern # git worktree add -b <branch-name> <PATH> <remote>/<branch-name> git worktree add -b fix-aws-service-cnsn /tmp/project origin/fix-aws-service-cnsn

This will create a new directory /tmp/project that you can review the branch fix-aws-service-cnsn from the remote origin. If you have setup different remotes locally you can check for the name of it with git remote -v

Using Git from Python

GitPython is a python api for your git repos, it can be quite handy when you need to work with git from python.

I recently made myself a handy tool for making screenshots in python and it need to do a git commit and push from within the script. For this I reached for GitPython.

How I Quickly Capture Screenshots directly into My Blog

GitPython is a python library hosted on pypi that we will want to install into our virtual environments using...

...

pipx on windows

Python, click install

Edit the System Environment Variables

Environment Variables button

Add the following path to your users Path Variable

⭐ httpie cli

I came across cli from httpie, and it’s packed with great features and ideas.

🥧 HTTPie CLI — modern, user-friendly command-line HTTP client for the API era. JSON support, colors, sessions, downloads, plugins & more.

Python sys.excepthook

Sometimes you just want python to do something else when you hit an exception, maybe that’s fire a text, slack message, email, or system notification like I wanted.

I am working on a quick and dirty python script designed to take screenshots and land them on my website in a single hotkey. With it being designed to run with a hotkey, if it were to error I would not see it.

I could have gone down a logging route, but honestly this is meant to be quick, dirty, and work on my system for me. I just want to get it in my system notification.

Python exposes sys.excepthook for just this case. Here is what I ended up doing to fire a system notification as well as printing the message. Yaya a log would be mroe appropriate, but this is designed to just get done quick and do the job I want it to do.

A TTY Can Save Your Bacon

I recently was unable to boot into my home Linux Desktop, it got stuck at diskcheck fsck. I found that I was able to get in to a tty through a hotkey.

There’s probably more to it, but to me its a full screen terminal with zero gui, not even your gui fonts. It does log into your default shell so if you have a comfy command line setup it will be here for you even though it looks much different without fonts and full colorspace.

Normally you have 6 TTY’s running, the first is dedicated to your desktop manager, which is your login screen it might be something like gdm or lightdm.

pygame events are queued | Don't make this mistake

pygame events are stored in a queue, by default the most suggested way shown in all tutorials “pumps” the queue, which removes all the messages.

You don’t necessarily need a full boilerplate to start looking at events, you just just need to pygame.init() and to capture any keystrokes you need a window to capture them on, so you will need a display running.

import pygame pygame.init() pygame.display.set_mode((854, 480))

get some events #

Let’s use pygames normal event.get method to get events.

events = pygame.event.get()

printing the events reveal this

Display Sprites in Pygame | Load and Blit

One of the most essential concepts of pygame to start making a game you will need to understand is loading images and blitting them to the screen.

blit stands for block image transfer, to me it feels a lot like layering up layers/images in photoshop or Gimp.

I started by making a spotlight in Gimp, by opening a 64x64 pixel image and painting the center with a very soft brush.

This is what it looks like

Mixing Colors at the Command Line

From the same Author that brought us command line essentials like fd and bat written in rust comes pastel an incredible command-line tool to generate, analyze, convert and manipulate colors.

You can install from one of the releases, follow the instructions for your system from the repo. I chose to go the nix route. I have enjoyed the simplicity of the nix package manager being cross platform and have very up to date packages in it.

Pygame Boilerplate Apr 2022

I’m poking a bit into gamedev. Partly to better understand, partly because it’s stretching different parts of my brain/skillset than writing data pipelines does, but mostly for the experience of designing them with my 9yo Wyatt.

I’ve seen several pygame boilerplate templates, but they all seem to rely heavily on globl variables. That’s just not how I generally develop anything. I want a package that I can pip install, run, import, test, all the good stuff.

What currently have is a single module starter package that is on github so that I can install it and start building games with very little code.

Since it’s a package on GitHub you can install it with the git+ prefix.

Unzip minecraft mods to their directory from the command line

This morning I was trying to install a modpack on my minecraft server after getting a zip file, and its quite painful when I unzip everything in the current directory rather than the directory it belongs in.

So I’ve been struggling to get mods installed on linux lately and the easiest way to download the entire pack rather than each mod one by one seems to be to use the overwolf application on windows. Once I have the modpack I can start myself a small mod-server by zipping it, putting it in a mod-server directory and running a python http.server

python -m http.server

Downoading on the server #

Then I go back to my server and download the modpack with wget.

wget 10.0.0.171:8000/One%2BBlock%2BServer%2BPack-1.4.zip

Unzip to the minecraft-data directory #

Now I can unzip my mods into the minecraft-data directory.
